I became a Verizon customer last year when I purchased a Samsung Galaxy Book S and a data plan for it. I eventually replaced the Book S with an iPad Air purchased from Verizon.
Yesterday, I added my iPhone to the plan, and there was not a way to share the data without treating the iPad as one line and the phone as another, which, of course, will boost my monthly charges considerably in the long run.
I remember when I was on our family AT&T plan, a device like a tablet could be added to the plan for $10 and it shared the data with the other members. I have also been a Google Fi customer, and $10 could buy and extra data SIM for a device like a laptop or tablet and the data would be shared with the allotment for the plan.
I care less about "unlimited" data than simply having a pot of, say, 10GB of data between my devices that would be more than enough for me.
All things considered, an iPad does not need a line. You can't make phone calls from it. You can't register the My Verizon app with it to check your account because the authentication code comes via SMS to the iPad number, which the iPad cannot receive.
I am wondering if there is an economical way to keep both the phone and the iPad on a more economical plan, even it if is not "unlimited".
